The power grid of a certain oilfield covers multiple substations, with its power supply spanning complex geographical environments such as deserts and gobi areas. As oilfield digital transformation deepens, traditional energy management methods can no longer meet the demands of modern oilfield precision management and cost control. In response to the national "dual carbon" strategy and the goal of building a green and smart oilfield, it has become essential to deploy a highly reliable, wide-coverage, and intelligent remote meter reading and monitoring system.

Pain Points

The distances between multiple substations are significant. Traditional manual meter reading and inspection not only consume a lot of time and labor but also result in delayed data consolidation. Moreover, in harsh weather conditions, work efficiency is severely impacted.

Some substations lack stable wired network coverage. Traditional power line carrier communication is prone to cross-regional interference and load fluctuations, leading to data loss or delays. As a result, wired data collection methods are not fully suitable.

Front-end metering devices (electricity meters) use various protocols (such as DL/T645, Modbus, IEC104, etc.) and non‑standardized data interfaces. This makes it difficult to uniformly aggregate and standardize multi‑source heterogeneous data, preventing accurate analysis on the back end.

Solution

To address these challenges, WideIOT deploys energy data collection gateways. These gateways can collect data from multiple smart meters simultaneously, transmitting electrical parameters — including voltage, current, power, power factor, and energy consumption — to a remote monitoring and management platform via 5G/4G wireless networks. This enables visualized data display, abnormal alerts, automated billing, and multi‑dimensional analysis, providing reliable support for energy management and optimization.

Key Features

1. Industrial‑Grade Design

Supports a wide temperature range (-20°C to 70°C), resists electromagnetic interference, and features an industrial‑grade protective housing suitable for harsh outdoor oilfield environments.

2. Multi‑Protocol Compatibility

Includes a built‑in library of protocols, supporting power industry standards such as IEC104, DL/T645, and Modbus. Protocol conversion is available to solve the challenge of connecting heterogeneous devices.

3. Edge Computing Capability

Supports data filtering, formula‑based calculations, and alarm threshold uation. Enables "no raw data upload, anomalies reported immediately", significantly reducing server load.

4. Data Resume on Interruption (Store & Forward)

In case of network failure, the gateway automatically caches collected data locally. Once the network is restored, historical data is automatically retransmitted to ensure zero data loss.

5. Abnormal Alerts

Preset threshold rules can be configured on the gateway. When conditions such as current overload, low power factor, or abnormal voltage are detected, the system quickly pushes alerts via WeChat, SMS, or email.

6. Multi‑Dimensional Analysis

Management personnel can perform energy statistics (peak, flat, valley), loss comparisons, and trend predictions by substation, by circuit, or by department (e.g., oil extraction plant, residential area), enabling scientifically sound decision‑making.
